UNITED STATES PATENT OFFICEo JOHN HERNLY, OF EAST HEMPFIELD, PENNSYLVANIA.

`IMPRVEMEMNT IN CORN-FLOWS.

Specification forming part of Letters Patent No. 1,031, dated December 10, 1338.

To ai@ 'whom it may concern Be it known that I, JOHN HERNLY, ot' East Hemptield township, in the county of Lancaster and State ot' Pennsylvania, have invented a new and useful Improvement in the Plowing and Dressing of Corn, called Hernlys Gornllow 5 and I do hereby declare that the following is a full and exact description.

Atriangular frame, AA and B, Figures l and 2, is made of three pieces ot' timber ot' about three inches by ve inches in thickness. The two side pieces are about four and a half feet long, the other or end beam about three feet four inches. A tong, O, Figs. l and 2, is inserted in the frame at the point infront where these side pieces meet, in the same manner as the tongue and hounds of a wagon are fixed. Near to the hind end of those side pieces a piece of wood is inserted into each from beneath of about afoot long and of nearly the samewidth and about two inches thick, which arecalled the mold-boards7D, Figs. 1,2,and 3. They are let in by a round tenon, so that they may be turned on the tenon when occasion requires. They are secured by pins through the end of the tenon, and kept rm by the iron rod F, hereinafter described.

Several bores may he made in the side pieces at different distances from the end, a b c d, Fig. 1, so that the mold-boards can be set forward or backward, according as the mold is to be thrown nearer to or farther from the cornrows. On the inside ot' the lower end of these mold-boards is a plate of iron, extending below the mold-boards, called the share,77 E, Figs. l, 2, and 3, from one-fourth to one-half inch thick and from twelve to twenty-four inches in length, about seven to ten inches deep at the foreend,and about one-haltet thisdepth at the hind end, having its lower edge turned a little inward. These shares are fastened upon the inner side of the moldboards by screws, and may be moved farther front or back by changing the place of the screws. An iron rod, F, Figs. l and 2, is fastened t0 the fore side of each mold board and running up through the side pieces in an anglingdireetion toward the i'ore end thereof, with a screw at top, as at G, Figs. l and 2, by means of which rod the mold-boards and shares can be turned more in a line with the furrow, making it narrow, or more across the furrow, making itwider, thus bringing less or more ground to the corn row. By placing the mold-hoardsin the proper holes in the beams and regulating them by the screw-rods two furrows can lbe made at one time and in [ine order for planting corn.

Two handles-one nearthecenter of the hind or end beam, the other above the left-hand side, lil-enable the farmer to walk in the furrow and manage his plow while o ne share runs on each side ot' the row. This plow is drawn by two horses, and is fastened to the helms of each by a cross-bar at the point of the tongue. It can be accommodated to one horse. By means ofthe tongue so fastened and these handles the plowman may direct his plow at pleasure.

What I claim as my invention, and desire to secure by Letters Patent, is-

The peculiar manner of constructing, attising, and connecting the mold-boards so as to admit of their being shifted and turned so as to regulate the distance apart and the breadth of the furrows, as herein described.

JOHN H ERNLY.
